Abstract

The invention relates to a gas conversion and cooling device, and particularly relates to a device used for CO gas conversion and cooling. The objective of the invention is to overcome the problem that the efficiency of converting CO gas into H2 of CO gas conversion and cooling devices at present is low and cannot meet requirements of methanol synthesis devices and the problem that the heat recovery rate is low. Raw gas is fed from a raw gas compressor to a degreaser, a preheating converter, a main-heat converter, a first converting furnace, a medium-pressure waste heat recoverer, the main-heat converter, a separator, a second converting furnace, a sub-medium pressure waste heat recoverer, the preheating converter, a boiler feed water preheater, a desalted water preheater, a cooler, an amino washing separating tower, a stripping tower, a condensate heat exchanger, a condensate cooler, a final cooler and a gasification circulating water pipe in order to perform a conversion reaction. The device is suitable for conversion reactions.

Description

technical field [0001] The invention relates to a device for gas shifting and cooling. Background technique [0002] Affected by the increasingly tense oil resources in recent years, my country's coal chemical industry has entered a stage of rapid development. In view of the fact that entrained bed coal gasification technology has many advantages such as low requirements on coal quality, high effective components of syngas and low operating costs, it has become a key field for the development of modern coal gasification technology. [0003] The CO shift process is widely used in ammonia synthesis units and hydrogen production units. It is a major part of the purification process, and its process position is set after the gasification or conversion process. Different transformation processes are mainly reflected in changes in the number of transformation reaction stages, reaction temperature, and heat recovery, which mainly depend on the performance of the transformation cat...
